Dominant and Recessive Traits

Dominant traits are expressed in an organism's phenotype when at least one dominant allele is present, while recessive traits are only expressed when two copies of the recessive allele are present, resulting in a phenotype that reflects the recessive characteristic.

Overview

Dominant and recessive traits are fundamental concepts in genetics that explain how traits are inherited from one generation to the next. Dominant traits require only one dominant allele to be expressed, while recessive traits need two recessive alleles. Understanding these concepts is essential for...

Key Terms

Allele
Different forms of a gene that can exist at a specific locus.

Example: The gene for flower color may have a purple allele and a white allele.

Genotype
The genetic constitution of an individual, represented by alleles.

Example: A genotype of 'Aa' indicates one dominant and one recessive allele.

Phenotype
The physical expression of a genotype, observable traits.

Example: A plant with a genotype 'AA' will have a purple flower phenotype.

Homozygous
Having two identical alleles for a particular gene.

Example: An individual with the genotype 'aa' is homozygous recessive.

Heterozygous
Having two different alleles for a particular gene.

Example: An individual with the genotype 'Aa' is heterozygous.

Mendelian Inheritance
Patterns of inheritance that are characteristic of organisms that reproduce sexually.

Example: Mendel's pea plant experiments demonstrated these patterns.
